In short. Removing the outer layer takes pigment and sun damage with it, and asks for weeks of open healing. What that trade includes, and why colour risk matters most.
Key points
- Removal buys a more direct change to surface lines and uneven pigment, and it pays for that with an open healing phase and with the risk that the new surface forms a different colour from the skin around it.
- Both sides of that trade are settled before treatment, not after.
Removal of the surface layer is the more direct of the two routes in this comparison. It does not ask the skin to repair itself underneath an intact surface; it takes the surface away and requires the skin to grow a new one. Understanding what that costs, in healing and in risk, is most of understanding the treatment.
What is actually removed
The outermost layer of skin is taken off to a depth the operator chooses, and that depth can vary between areas of the face. The layer is thin, and it is where the pigment-producing cells sit, where sun damage accumulates, and where fine lines form. Removing it, and letting a new layer replace it, is why this route changes uneven colour and surface lines more directly than treatments that leave the layer in place.
The weeks that follow
The skin left behind is a wound. It is open, it weeps, and it closes over weeks rather than days, with prescribed cleansing and ointment and, in many plans, antiviral cover for patients with a history of cold sores. The face is red when it closes and remains red well beyond the closure. Sun exposure during this period is the most damaging thing a patient can allow, because the new layer is forming its pigment as it heals.
The trade this route makes
Removal buys a more direct change to surface lines and uneven pigment, and it pays for that with an open healing phase and with the risk that the new surface forms a different colour from the skin around it. Both sides of that trade are settled before treatment, not after.
Why the colour risk is the one that matters most
Skin responds to injury by making pigment, and how much it makes varies between people. When the layer holding the pigment is removed and regrows, the new layer can be darker or lighter than the surrounding skin. In some patients that fades over many months; in others only partly; in a few it persists. Skin that tans easily and rarely burns carries the highest risk, which is why an ablative plan may be declined, staged, or replaced with the other route in this comparison.
What it does not do
It does not tighten skin that has loosened. Firmness can improve as a by-product of healing and some patients notice it, but this is not a lift and should not be chosen as one. It does not remove a scar; it can improve how a scar looks. And it does not stop the process that caused the complaint, so the change it produces is maintained rather than finished.
Reasons this route is declined
- Skin that tans easily and rarely burns, where a lasting colour difference would outweigh the benefit being sought.
- A pigment disorder such as melasma, which inflammation of this kind can worsen rather than improve.
- Skin that is inflamed or infected, or a patient who cannot protect the healing period from sun.
Anyone describing this route as a way to look years younger is describing something the treatment does not do. What it can do is change surface lines and uneven colour, in skin assessed as able to heal from it, at a cost of weeks rather than days.
Frequently asked questions
How long is the skin actually open after resurfacing?
The closure is measured in weeks rather than days, and it varies with how deeply the surface was taken and how the individual heals. The face is red when it closes and stays red for longer than the closure took. Prescribed cleansing and ointment continue through that period, and sun exposure during it is the single most damaging thing a patient can allow.
Why does the new skin sometimes come back a different colour?
Because the layer that was removed is the layer that holds the pigment-producing cells, and skin responds to injury by making pigment. The new layer can form darker or lighter than the surrounding skin. In some people that difference fades over months, in others it fades only partly, and the risk is highest in skin that tans easily.
Will my skin look younger afterwards?
It can look smoother in the lines formed by sun, and more even in colour, in skin that heals without a pigment problem. What it will not do is reverse the ageing process or restore the volume and position that a lift changes. Anyone promising a particular number of years off the face is describing something this treatment cannot deliver.
Risks & Limitations
- No result can be guaranteed, and healing times vary between people.
- Pigment change after an ablative treatment may fade only partly, or not at all.
- Heat delivered below the skin can injure the fat beneath it, and that change is lasting.
- Neither route removes a scar or tightens loose skin, and further treatment may be needed.
When to Seek Care
- Blistering, spreading redness or worsening pain in a treated area.
- Fever, or discharge or warmth from skin that is healing.
- A cold sore outbreak after treatment in a patient with a history of them.
- Any new or changing mark on treated skin, which should be examined rather than observed.
